    Converting acceleration to velocity to displacement graph

    Homework Statement the task is to explain how to find the velocity vs time graph from an acceleration vs time graph and how to find a displacement vs time graph from the resulting velocity vs time graph, without using an intergral. Homework Equations The Attempt at a Solution i...
